We should be validating the Rx count on the Rx struct,
not the Tx struct. There is no real change here, rx_stats
and tx_stats are instances of the same struct.

The lifetime of page pools is tied to NAPI instances,
and they are destroyed before NAPI is deleted.
It's safe to link them up.

ATU Load operations could fail silently if there's not enough space
on the device to hold the new entry. When this happens, the symptom
depends on the unknown flood settings. If unknown multicast flood is
disabled, the multicast packets are dropped when the ATU table is
full. If unknown multicast flood is enabled, the multicast packets
will be flooded to all ports. Either way, IGMP snooping is broken
when the ATU Load operation fails silently.
Do a Read-After-Write verification after each fdb/mdb add operation
to make sure that the operation was really successful, and return
-ENOSPC otherwise.

====================
net: bcmgenet: revise suspend/resume
This commit set updates the GENET driver to reduce the delay to
resume the ethernet link when the Wake on Lan features are used.
In addition, the encoding of hardware versioning and features is
revised to avoid some redundancy and improve readability as well
as remove a warning that occurred for the BCM7712 device which
updated the device major version while maintaining compatibility
with the driver.
The assignment of hardware descriptor rings was modified to
simplify programming and to allow support for the hardware
RX_CLS_FLOW_DISC filter action.

If the network interface is configured for Wake-on-LAN we should
avoid bringing the interface down and up since it slows the time
to reestablish network traffic on resume.
Redundant calls to phy_suspend() and phy_resume() are removed
since they are already invoked from within phy_stop() and
phy_start() called from bcmgenet_netif_stop() and
bcmgenet_netif_start().

The bcmgenet_power_up() function is moved from the resume method
to the resume_noirq method for symmetry with the suspend_noirq
method. This allows the wol_active flag to be removed.
The UMAC_IRQ_WAKE_EVENT interrupts that can be unmasked by the
bcmgenet_wol_power_down_cfg() function are now re-masked by the
bcmgenet_wol_power_up_cfg() function at the resume_noirq level
as well.

The functions bcmgenet_dma_disable and bcmgenet_enable_dma are
only used as part of dma initialization. Their functionality is
moved inside bcmgenet_init_dma and the functions are removed.
Since the dma is always disabled inside of bcmgenet_init_dma,
the initialization functions bcmgenet_init_rx_queues and
bcmgenet_init_tx_queues no longer need to attempt to manage its
state.

Currently on stable trees we have support for netmem/devmem RX but not
TX. It is not safe to forward/redirect an RX unreadable netmem packet
into the device's TX path, as the device may call dma-mapping APIs on
dma addrs that should not be passed to it.
Fix this by preventing the xmit of unreadable skbs.
Tested by configuring tc redirect:
sudo tc qdisc add dev eth1 ingress
sudo tc filter add dev eth1 ingress protocol ip prio 1 flower ip_proto \
tcp src_ip 192.168.1.12 action mirred egress redirect dev eth1
Before, I see unreadable skbs in the driver's TX path passed to dma
mapping APIs.
After, I don't see unreadable skbs in the driver's TX path passed to dma
mapping APIs.

Andy reported the following build warning from head_32.S:
In file included from arch/x86/kernel/head_32.S:29:
arch/x86/include/asm/pgtable_32.h:59:5: error: "PTRS_PER_PMD" is not defined, evaluates to 0 [-Werror=undef]
59 | #if PTRS_PER_PMD > 1
The reason is that on 2-level i386 paging the folded in PMD's
PTRS_PER_PMD constant is not defined in assembly headers,
only in generic MM C headers.
Instead of trying to fish out the definition from the generic
headers, just define it - it even has a comment for it already...

sco_conn refcount shall not be incremented a second time if the sk
already owns the refcount, so hold only when adding new chan.
Add sco_conn_hold() for clarity, as refcnt is never zero here due to the
sco_conn_add().
Fixes SCO socket shutdown not actually closing the SCO connection.

Automatically configure the altsetting for HCI_USER_CHANNEL when a SCO
is connected.
The motivation is to enable the HCI_USER_CHANNEL user to send out SCO
data through USB Bluetooth chips, which is mainly used for bidirectional
audio transfer (voice call). This was not capable because:
- Per Bluetooth Core Spec v5, Vol 4, Part B, 2.1, the corresponding
alternate setting should be set based on the air mode in order to
transfer SCO data, but
- The Linux Bluetooth HCI_USER_CHANNEL exposes the Bluetooth Host
Controller Interface to the user space, which is something above the
USB layer. The user space is not able to configure the USB alt while
keeping the channel open.
This patch intercepts the HCI_EV_SYNC_CONN_COMPLETE packets in btusb,
extracts the air mode, and configures the alt setting in btusb.
This patch is tested on ChromeOS devices. The USB Bluetooth models
(CVSD, TRANS alt3 and alt6) could work without a customized kernel.
